Hi S7e9h3n,
I'm confused as well. This should not report this way, but one processor with 4 cores / 4 threads, as on previous screenshots.
Kyosen is modifying MSRs, so this can make cpuz wrongly detect some things, this may explain. He will help me figuring out anyway.

AMD's power monitor reports the Core VID, I'm currently adding that in cpuz as well. But the real VCORE is always better, and in this case cpuz did not detect the sensor chip.

I'm also preparing a small tool to change multiplier on the fly for each core. Kyosen already does it, but this is not very convenient. A slider will make things much easier for him.
